Determine the volume of the cone
The volume of a square pyramid is:
Where
a = base dimension
From the attachment, the base dimension of the square pyramid is 2r.
So:
The volume becomes;
To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.
So, we have:
Open bracket;
Cancel out 4
The above can be written as:
So, we have:
or
7 17/18. Put them both over 18 and add so they have the same denominator

Answer:
21.42
Step-by-step explanation:
Imagine it as a full circle. 3 x 4 will give you the diameter of a full circle, which is 12. circumference = pi x diameter. so 12 pi (we can work that out later). now for the quater circle, divide it by 4, so 3 pi. Then you have the 2 extra edges which are both 2r, so 6 each. finally, you have 3 pi plus 12 which = 21.42
